Proposed Soaring Index on Google Maps
By Ted MacKechnie, 5/9/2009
AutoSOAR (soaring forecast program) sends a Soaring Index to the SGX Google Maps
Sub-system. AutoSOAR (on the autoPC) produces and sends a file (SORMAP) to the
web via LDAD. The SORMAP file is a comma delimited file with the daily soaring
forecast data (date,site,lat,lon,index,etc). I have asked Stephanie Sullivan to write the
Google Module to plot the index. The index rates thermal strength (ft/min) as Poor<200,
Fair<400, Good<800, Excellent<1200, and Super>1200.
The google module plots a colored icon based on the index., i.e., poor=blue, fair=green,
yellow=good, orange=excellent, and super=red. The user of the interface can click the
icon to see the text data (site, elev, maxT, triggerT, lift, thermal tops, CCL, thermal
index) in a popup box. The icon and the data box are plotted on a google
terrain/map/satellite image of the area. The map can be zoomed and dragged.
The Soaring Forecast is also available as tabular text at
and on AWIPS as LAXSRGSGX.
The AutoSOAR program (written in Turbo-C by Ted MacKechnie of SGX) has been
producing the Soaring Forecast since 1997. The forecast is based on site maxt and
elevation, and uses the Mirimar morning or afternoon sounding to compute the soaring
parameters. The Soaring Forecast is viewed by aviation users (power, sailplane, hang-
glider and RC-glider pilots), and by fire weather users (for plume dominated fire
